Specification of Letters Patent.

Application filed April 10, 1907. Serial N0. 387,351.

and the invention has for its object to provide a novel coupler wherein positive and reliable means are employed for connecting two cars together, said means being easily and quickly operated to release the coupled cars.

Another object of this invention is to provide a novel car coupler which will be strong,

and durable, comparatively inexpensive to manufacture, composed of comparatively few parts, and highly efiicient for the purpose for which it is used.

With the above and other objects in view,

which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described and then specifically pointed out in the appended claim, and re ferring to the drawing forming part of this specification, like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a horizontal sectional view of two coupler heads constructed inaccordance with my invention, taken on line 11 of Fig. 4 illustrating the heads connected together, Fig. 2 is a perspective view of a coupling knuckle Fig. 3 is a similar View of a locking member, Fig. 4 is a longitudinal sectional view online 4-4 of Fig. 1 but upon a reduced scale, and Fig. 5 is a trans verse section on line 5-5 of Fig. l'upon a reduced scale.

To put my invention into practice, Iconstruct a coupler head of strong and durable metal, and provide the same with a jaw 2 and with forwardly extending arms 3 having extensions 4, said extensions being shouldered, as at 5; the arms 8 providing a horizontal slot 6 and in said slot is pivotally mounted, as at 7, a knuckle 8, said knuckle having a face 9, inclined to the longitudinal axis of the coupler anda curved edge 10 and a tongue 11.

Pivotally mounted, as at 12 in the head 1 is a locking member 14, said member hav- I ing a similarly inclined edge 15. The memher is normally held .in a fixed position by a spring 16 secured to the head 1, and connecting with said member is a chain or cable 17 which passesv through an opening 18 formed in the head of the coupler and is connected to a conventional form of uncoupling mechanism, such as commonly used in connection with railway cars.

The large end of the locking member 14 is adapted to strike against the shoulder 5 of the extension 4 and limit its inward movement, the member when in this position preventing the knuckle 8 from swing ing open. To release the knuckle 8, the locking member 14 is pulled outwardly until it clears the inclined face 9 of the knuckle, and when the adjoining head is pulled outwardly the knuckle will swing until the extension 4 of the adjoining head the aw '2 knuckle 8 of one jaw with relation to the locking knuckle of the adjoining jaw. The opening of the knuckle 8 is limited by the shoulder 5 of the extension 4, the knuckle movement of the locking member 14. It will thus be observed that the knuckles take a positive grip upon theextensions4 and cannot be forced open until the locking members are swung outwardly. The inclined edges and faces of the knuckles and locking members permit of two coupler heads being automatically locked together.

the'fknuckles and locking-members used in connection with the same, therefore,,li do employed for releasing the locking members. 7 It IS obvlous that such changes in the size, proportlon and minor details of construcclears the tongue 11 of the knuckle.

hat I claim and desire to secure by Letters Patent, is

A coupler comprising a head having a jaw at one side and ari iarm at the-other side thereof, a knuckle pivotally mounted on said arm and provided with a tongue, said knuckle having a face and a curved edge, said face being inclined to the longitudinal axis of the coupler, a locking member having an enlarged free end and pivoted at its smaller end in the head, said locking member having its free end inclined and further having one side substantially segment shaped in contour and its other side curved to provide a pocket to receive the tongue of a cooperating knuckle, a laterally extending apertured lug projecting from one side of said member at the free end thereof, a spring having one end fixedly secured within the head and engaging that. side of the locking member provided with the apertured lug, said spring retaining said locking
